Worm farms are great for redworms and brandlings which are relatively small compared to the lobworms that my gourami goes crazy about. Lobworms don't seem to be attracted to my composting heap, they're more of a deep soil worm so you have to put a bit more work into collecting them, although they do come to the surface on mild dark nights.
Imagine the poop pile from a twenty foot nightcrawler.There are some rather large earth worm species,if u can grow one to twenty feet u could be set all year.

I have read that worm castings are great for the gardenI was just in my worm bin and removed quite a bit of worm poop for the garden
